Mental Health

A state of emotional, psychological, and social well-being that influences how a person thinks, feels, behaves, relates to others, and responds to life’s challenges.

Mental health exists on a continuum and can change throughout life. It is influenced by biological, psychological, social, environmental, and other factors.

Mental health is not synonymous with the absence of mental illness; a person can experience a mental health difficulty without having a diagnosed mental disorder, and mental health can change over time.

QUICK FACT

Everyone has mental health, just as everyone has physical health.

COMMONLY CONFUSED WITH
